An interesting article in USA Today about ‘Phantom Vibration Syndrome’ – when you think your mobile is buzzing in your pocket only to find out it wasn’t! If you’re like me and always keep your mobile in the same pocket, you may have experienced this “habit of the brain”.

“When we learn to respond to a cellphone, we’re setting perceptual filters so that we can pick out that (ring or vibration), even under noisy conditions,” Lleras says. “As the filter is created, it is imperfect, and false alarms will occur. Random noise is interpreted as a real signal, when in fact, it isn’t.”
